1,8-Bis(allylthio)- and 1,8-bis(allylseleno)naphthalene monooxides underwent facile mulliallylic rearrangements to give 2-allyl-substituted naphtho[1,8-cd]-1,2-dithioles and naphtho[1,8-cd]-1,2 diselenoles under mild conditions via the sulfur-sulfur and selenium-selenium through-space interaction. The mechanism for the reaction has been determined by D-tracer and cross-over experiments.
1,8-双(烯丙基硫基)-和1,8-双(烯丙基硒基)萘单氧化物进行了简单的多元烯丙基重排,得到2-烯丙基取代的萘并[1,8-cd] -1,2-二硫代和萘[1,通过硫-硫和硒-硒的空间相互作用,在温和的条件下生成8-cd] -1,2二烯醇。反应机理已通过D-示踪剂和交叉实验确定。
